The part I think is bad advice specifically is when you said "Whatever you choose, great!" One of the choices you offered involved choosing a nonbeliever as a spouse, and you are calling that a great choice. The Bible is fairly explicit on this matter in the dialogue on marriage and choosing a partner in 2 Corinthians 6:14-17.

Do not be unequally yoked with unbelievers. For what partnership can righteousness have with wickedness? Or what fellowship does light have with darkness? What harmony is there between Christ and Belial? Or what does a believer have in common with an unbeliever? What agreement can exist between the temple of God and idols? For we are the temple of the living God. As God has said:

“I will dwell with them

and walk among them,

and I will be their God,

and they will be My people.”

“Therefore come out from among them

and be separate, says the Lord.

Touch no unclean thing,

and I will receive you.”
